OTS 4040 PSBT Transponder
Technical Specifications
The OTS-4011 line card offers the following capabilities:
- Transparent transport of OC-768/STM-256 service interfaces
- Supports channelized or concatenated framing
- Full C or L band tunable laser and broadband receiver for flexible wavelength provisioning and minimized sparing costs
- Enhanced Forward Error Correction with 8.5dB net equivalent coding gain for optimized reach up to 1,000km
- Spectrally efficient 22GHz FWHM bandwidth for operation at 50GHz channel spacing and through multiple (>10) cascaded [R]OADMs
- -19 to 0dBm transmit output power and -18 to 0dBm receive input power range for easy interoperability with existing DWDM systems
- Common CD and PMD link engineering rules as 10Gbps when deployed in conjunction with the OTS-4520 TDCM and OTS-4540 PMDCM
Applications
The OTS-4040 transponder enables cost-effective transport of OC-768/STM-256 client services into a 40Gbps DWDM wavelength for metro, regional and long-haul networks. It can be deployed in retrofit applications on existing 10Gbps DWDM networks, or to maximize capacity for greenfield deployments. For both applications, the use of spectrally efficient Phase-Shaped Binary Transmission (PSBT) modulation format enables operation on the 50GHz ITU grid and operation over multiple cascaded [R]OADMs with negligible penalty.
Operation at 50GHz channel spacing facilitates simplified 10Gbps and 40Gbps multi-haul networking. No special banding structure or alternating 10Gbps and 40Gbps channel plan is required to support mixed 10Gbps and 40Gbps DWDM networking. 10Gbps or 40Gbps wavelengths are completely interchangeable at any point in the network.
IP Next Generation Networking
Convergence of all telecommunications applications over IP, including bandwidth hungry video over IP, means that service provider networks must scale their IP networks considerably over the coming years to support this new demand. In response to this requirement, router vendors have developed new Terabit IP routers to support converged IP NGNs. These next generation IP routers offer interfaces at OC-768/STM-256 speed for optimum IP efficiency and DWDM systems must aggregate OC-768/STM-256 to support scalable IP NGNs. The OTS-4040 transponder provides a key building block for IP Next Generation Transport in metro, regional and long haul networks.
